Abstract

A large scale (1/60) experiment has been conducted in order to study fluid - structure interactions within an array of risers tensioned by mean of buoyancy-cans. Similitude rules have been derived assuming a pendulum like motion of the rigid Air Cans Assembly at the top of the riser, leading to define different models associated to each structural mode of the full-scale configuration. Vortex Induced Vibrations (V.I.V.) and Wake Interactions within the array have been measured. Experimental results concerning lock-in region, in term of reduced velocity and maximum vibration amplitudes are presented together with time domain series.
